Sarcoma or haematoma? If only it was that simple! Part 2.

Introduction: Imaging appearances and clinical presentation of soft tissue sarcoma and soft tissue haematomas are similar. It is imperative that sarcoma is differentiated from benign soft tissue lesions due to the poor outcomes and high morbidity associated with sarcoma.

Topic description: Part 2 of this pictorial review summarises the key ultrasound appearances of soft tissue sarcoma and soft tissue haematomas and some differential diagnoses.

Discussion: Ultrasound is the first line test in the investigation of soft tissue masses. With the overlapping ultrasound appearances of soft tissue sarcoma and soft tissue haematomas, it is essential that practitioners are aware of key ultrasound appearances and understand when to escalate cases for further investigation.

Conclusion: Sound knowledge of the clinical and sonographic features of soft tissue haematomas and soft tissue sarcoma as well as recognising potential differential diagnoses is fundamental to ensuring an accurate diagnosis, timely management and improved patient outcomes.
